Embodiment Construction

[0060] The invention provides a three-dimensional space intelligent positioning and distributed edge computing support method for the Internet of Things.

[0061] First, a set of available anchor nodes is constructed according to the effective communication range of IoT devices and the energy information of anchor nodes. In addition, the positioning unit is constructed according to the angle relationship between the anchor node and the IoT device, and the anchor node in the positioning unit is selected by the reference point selection theorem, and the mobile IoT devices scattered in the environment are analyzed by the three-dimensional space positioning algorithm. Intelligent positioning, and the position coordinates of the IoT device are corrected through the mean value of multiple positioning. If the mean error is less than the threshold, the position of the IoT device is obtained.

[0062] Then, path planning and computational offloading are dynamically performed using mobi...

Abstract

The three-dimensional space intelligent positioning and distributed edge computing support method of the Internet of Things of the present invention includes: acquiring the energy consumption of each anchor node and the distance information from the Internet of Things device, and constructing a set of available anchor nodes for each Internet of Things device; From the set of available anchor nodes, four non-coplanar anchor nodes are selected to construct a set of positioning units of the IoT device; using the anchor node information in the set of positioning units, the positioning coordinates of the IoT device are obtained, and using The average value of multiple positioning solves the location of the target IoT device; obtains the location and task request type of all IoT devices, uses the UAV base station equipped with the edge server to dynamically perform path planning to process requests from multiple IoT devices, and determines unloading Decision-making; the UAV sails according to the optimal path planning, approaching the IoT device, and the IoT device performs edge computing offloading.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to a three-dimensional space intelligent positioning and distributed edge computing support method of the Internet of Things. Background technique [0002] Driven by the Internet of Things (Internet of Things) technology, more and more smart devices are connected to the network and are widely used in various fields of production and life, such as performing environmental monitoring, target tracking, and risk warning. In many cases, these IoT devices are widely deployed in unmanned and even challenging areas, such as forests, deserts, and military areas, and need to be constantly moving to perform given tasks, such as object tracking and identification. However, many low-cost IoT nodes cannot afford the high cost of Global Navigation Satellite System (GNSSs) receivers and cannot effectively use GNSS such as GPS, BeiDou Navigation System, etc. for positioning. The mobili...
